optibelt OMEGA and optibelt ZR timing belts have beendeveloped for the use in high performance drives. Drive

speed is transmitted synchronously, i.e. without speedloss, and with a constant transmission ratio.

The optibelt OMEGA tooth profile significantly reducesthe running noise level. The teeth are designed to ensurethat they mesh perfectly, with minimal friction, into thepulley teeth. optibelt OMEGA timing belts run in HTDand RPPpulleys.

This technical manual contains all important informationf th blts usg. Futhm, th clculti mthdsfor the drive design with OMEGA, OMEGA HP, OMEGAFan Power,OMEGA HL and ZR timing belts are alsopresented.

The belt characteristics described may change due tovarious influences. Thus, the drives must be designedbased on their intended use (or in a way that comes closeto their intended use).

If you have any further questions, please make use ofthe free service offered by our Application EngineeringDepartment.

All optibelt OMEGA timing belts have inherent resistance tooil, heat, cold, ozone and tropical conditions. Speciallabelling is not required.

Oil resistanceThe limited oil resistance prevents the damaging effects ofmineral oils and greases, as long as these substances arenot in permanent contact with the timing belt and/or are notpst i lg qutitis. with icsd dmds fresistance, e.g. to mineral oils, the performance of theoptibelt OMEGA timing belts can be improved by usingspecial belt constructions. Please contact the optibeltApplication Engineering Department.

Temperature resistanceThe timing belt can withstand ambient temperaturesfm 30 C t +100 C. Tmptus utsid this glead to premature ageing and embrittlement of the timingbelts and thus to their premature failure. The temperatureresistance of optibelt OMEGA timing belts can be extendedusig spcil blt cstuctis, .g. up t +140 C. Plscontact the OPTIBELT Application Engineering Department.

Antistatic propertiesAntistatic properties enable the safe discharge of electro-static charges. This charging can have such a strong impact timig blts ith isufcit lcticl cductivity tht

there is the danger of ignition due to sparks. The use ofantistatic timing belts requires that the properties be checkedi ccdc ith ISo 9563, d is cmd by th issuf ispcti ctict. oMeGa HP d oMeGa HLtimig blts i pls 8M d 14M s ll s oMeGaFan Power tisttic ccdig t ISo 9563 bystandard and are thus labelled accordingly.

Noise emissionThe optimized tooth shape and the indent in the tooth tip ofth ptiblt oMeGa pmt sigictly l islevel. In combination with the newly developed materials,the noise level is further reduced, even at high speeds and

with high belt tensions.Operational lifeBelt designs with increased capacity can exceed thepotential operational life of standard designs many timesover, particularly for highly loaded or overloaded drives.Example: Dynamic tests with optibelt OMEGA HP show thatthe running times, compared to standard timing belts, areup to 18 times higher.

PRODUCT DESCRIPTIONOPTIBELT OMEGA HLTIMING BELTS

Structure

Top layer

Tension cord

Tooth

Fbic

Top layerThe top layer of the OMEGA HL as well as the the teeth,consists of a polychloroprene compound reinforced withmid bs. Thus, v m bsi sistt sufcis in contact with any reverse bend idler. The belt top layerptcts th tsi cd fm vimtl iucs.

Tension cordI ctst t th oMeGa HP ith glss cd, th oMeGa HL uss sigictly high stgth glss cd. Thus, thpower can be further increased by up to 25 %. The resist-c t shck lds is ls sigictly icsd.

Teeth

The considerably increased tooth strength (compared tooMeGa) is md pssibl by th us f mid bs ithe polychloroprene compound. This imparts very high toothstiffness as well as increased shear strength.

FabricThe shear strength of the teeth is enhanced by an extremelytough fabric. The shape of the OMEGA teeth and theminimal friction fabric enable a smooth meshing of the belttooth into the pulley groove. In addition, the special polyam-ide fabric is very wear resistant.

The new high performance timing belt forextremely high loads across the whole speedspectrumOPTIBELT has developed this belt in the sections 8M and14M especially for drives with high torques and severeshock loads. These types of drives can often be found ingeneral engineering.F this us, th stuctu d th mtil f th timig blthave been optimised in such a way that highest operationallibility cmbid ith ptiml cmic fcicy cbe achieved when re-designing a drive. Initially, the belt willbe available in the 8M section. optibelt OMEGA HL timingbelts are used in optibelt ZRS HTDpulleys or in RPP

timig blt pullys. F pplictis i th pullys, plscontact the OPTIBELT Application Engineering Department.A reinforced glass tension cord is used. This innovative glasscord stands out due to the combination of the following,important characteristics: gd sistc t shck lds vy high dymic sistc vy l pmt d lstic sttchTherefore, the belt performance can be increased by anadditional 15 %, compared to OMEGA HP. In contrast to anaramid cord, which also has a very high resistance to shockloading, the reinforced glass cord has a considerably lowerpermanent stretch during the running time. Aramid cord hasa high permanent stretch (see diagram) during running. The

minimal tension loss of the reinforced glass cord enables akeeping of the pitch and thus to a load which is distributedmore evenly on the teeth during running.In addition, the reinforced glass cord can also be used atmedium and high speeds while the use of the aramid cord islimited to low and medium speeds. In contrast to the aramidcord, the reinforced glass cord enables a considerableextension to the range of applications.

Structure

Application example: lawn mowers

Top layerTh blt tp ly csists f xibl plychlpcompound which protects the tension cord from externaliucs. I dditi, it ffs limitd sistc t miloils and humidity as well as protection from frictional wearand tear.

Tension cordThe tension member is composed of a pair of countertistd glss b cds. Ths tsi cds hv hightsil stgth, vy high xibility d vy l sttch.

TeethJust like the belt top layer, the teeth consist of a polychloro-

prene compound guaranteeing high shear strength.The dimples in the teeth promote quiet running.

FabricThe polyamide fabric protects the teeth from premature weard tth t cckig. at th sm tim, th l cf-cient of friction lowers the operating temperature and helpsto reduce the running noise.

High performance optibelt OMEGA timing belts are theresult of a continuing development process. Operationalexperience with optibelt ZR and optibelt HTDhas beenapplied to this belt generation. Endless optibelt OMEGAtiming belts set the standard for synchronous performanceand for positioning drives.Th gmty f th ptiblt oMeGa tth pl hs b

developed to run in the established, curvilinear timing beltpulleys. optibelt OMEGA timing belts can be used in 3M,5M, 8M and 14M HTDpully pls. ptiblt ZrS HTD

timing belt pulleys are standard items in our range with pilotbores or bored for optibelt TB taper bushes. In addition, allOMEGA timing belts can also be used in RPPtiming beltpulleys. Special timing belt pulleys for optibelt OMEGAtiming belts are not required.

Top layer

a xibl blt bckig mbds th tsi lmt dsupports it against the reverse idlers. The top layer consistsf xibl high qulity chlp cmpud. Thisprotects the tension cord from oil, humidity, friction andwear and tear.This top layer has some inherent resistance to mineral oils,but not to vegetable oils and water soluble cooling andcutting oils.

Tension cordTh tsi cd is ctiuus, spilly ud glss b.This material has a high tensile strength and is extremelyxibl. Th l-sttch pptis f th tsi cd suthat the pitch of the belt corresponds to the pitch of thepulley even when under strain.

TeethThe teeth are made of a shear and wear resistant rubbercompound vulcanised to form a unit with the belt back. Theshape and arrangement of the teeth are such that the pulleyengages the belt teeth precisely and with minimum friction.As long as six teeth or more are in mesh on the small pulley,the complete capacity of the timing belt can be used withoutany deduction.

Tooth pitch is the distance from the centre of one tooth to thecentre of the next measured at the pitch line, which corre-sponds with the level of the tension cord. The pitch or datumdiameter of the pulley is a theoretical dimension which liesoutside the outer diameter.

PRODUCT DESCRIPTIONSTANDARD PROPERTIES / SPECIAL DESIGNS

optibelt ZR timing belts with angled sidesoptibelt ZR timing belts with angled sides can be customisedfor special applications.Special lengths, widths, tooth pitch or open-ended versionsof optibelt ZR timing belts and the minimum order quantitiesare available on request.

All optibelt ZR timing belts are oil-, heat- and cold-resistantas standard. Special labelling is not required.

Oil resistanceThe inherent oil resistance prevents the damaging effects ofmineral oils and greases, as long as these substances arenot in permanent contact with the timing belt and / or aret pst i lg qutitis with icsd dmds fresistance, e.g. to mineral oils, the performance of theoptibelt ZR timing belts can be improved by using specialconstructions. Please contact the optibelt ApplicationEngineering Department for more details.

Temperature resistanceThe timing belt can withstand ambient temperatures from 30 C t +100 C. Tmptus utsid this g ldto premature ageing and embrittlement of the timing beltsand thus to their premature failure. The temperature resist-ance of Optibelt ZR timing belts can be extended usingspcil cstuctis, .g. up t +140 C. Pls ctct thOPTIBELT Application Engineering Department for moredetails.

Anti-static propertiesAnti-static properties enable the safe discharge of electro-static charges. This charging can have such a strong impact timig blts ith isufcit lcticl cductivity tht

LOAD FACTORS

Total load factor c2The total load factor c2is comprised of the basic load factorc0plus two further loads c3and c6.

Basic load factor c0The basic load factor c0takes into account the daily operat-ing time, the type of drive and the prime mover. As it isalmost impossible to put all the possible combinations ofprime mover / driven unit / environmental conditions in ashortened form which conforms to standards, the servicefactors shown here are given only as a guideline. Theclssicti f th k mchi is dpdt threspective present load type.

With frequent starts and stops or continual revers-ingoperation, the selected total load factor c2should be higher than the ratio between startingtorque and nominal torque. If there is a brake onthe prime mover the same procedure shouldapply for the braking torque, if the brake is usedfrequently.

BELT TENSION

Belt tension for optibelt OMEGA HP/optibeltOMEGA HL and optibelt OMEGA timing beltsF pp p tsmissi d f chivig acceptable belt service life, the correct belt tension is ofthe utmost importance.Too low or too high belt tension will lead to the prematurefailure of the timing belts. Over tensioning often leads tobearing failure on the prime mover or the driven machine.expic shs tht uscitic blt tsiig mthds,such as the thumb pressure method, are not suitable forapplying the optimum tension to the drive for maximumfcicy d div/big lif. It is thf cmmd-ed that the correct static belt tension should be calculated

for each drive. Due to their extremely low-stretch characteris-tics OPTIBELT timing belts do not require any further tension-ing after correct installation, if properly used.SymbolF = tst fc [n]Sa = sttic shft ldig [n]Sn3 = cicumftil fc t b ffctivly tsmittd [n]Ea = blt dcti f giv sp lgth [mm]L = sp lgth [mm]
